How to adjust output voltage:

· Vision Vapros Spinner II is capable of outputting voltage from 3.3v to 4.8v.
· The bottom scale indicates the position of voltage output level.
· Rotate the bottom spin to align the red line with the bottom scale to arrive the voltage output level as marked in number.
· The red line on bottom spin can stay at any position along the scale between 3.3v and 4.8v to fine-tune your voltage output, despite the four locking position at 3.3v, 3.8v, 4.3v and 4.8v.
· Please be aware that the red line moves between 3.3v and 4.8v along the scale and do not push the red line on bottom spin to go over the 3.3v clockwise and 4.8v counter-clockwise; it may damage the battery if being pushed forcefully.
